D.All interior angles are 90 degrees
Use tangent
tan=opposite/adjacent
tan(54)=x/150
multiply by 150
150×tan(54)=x
206.5=x (approximately)
Answer:
$3.50
Step-by-step explanation:
Given:
$10 for a 6, $7 for a 5, $4 for a 4, and no payoff otherwise
P(6) = 1/6 ; p(5) = 1/6 ; p(4) = 1/6 ; p(1,2or3) = 3/6 = 1/2
P(x) ____ 1/6 _____ 1/6 _____1/6 _____1/2
x______ 10 _______ 7 _____ 4 _______ 0
Expectwd value ; E(x)
Σx*p(x) = (1/6 * 10) + (1/6 * 7) + (1/6 * 4) + (1/2 * 0)
E(x) = 3.50
The rectangular prism has measures 6 units by 6 units by x units,
Thus, the volume is 6*6*x = 36x (units cubed)
The surface area of the prism is
2(x*6+x*6+6*6)=2(6x+6x+36)=2(12x+36)=24x +72 (units squared.
36x=24x +72
36x-24x=72
12x=72
x=72/12=6
Answer: x=6
It is equal to 50% because you move the decimal places two times to the right. :)
